Description

Technical Field

[0001] The utility model relates to the technical field of switches, and more specifically to a light touch switch. Background Art

[0002] A touch switch, also called a micro switch, is an electronic switch. It is practical to turn on the switch by lightly pressing the switch button. When you release your hand, the switch is turned off. The metal spring inside is forced to bounce to achieve on and off. Touch switches have the advantages of small contact resistance, small error of precise operating force, and diversified specifications. They are widely used in electronic equipment.

[0003] The cover plate arranged on the existing touch switch has plug plates on both sides, so that the overall circumference includes metal sheets, which makes it impossible to use a robot arm for installation. Most of the existing ones are manually installed on the circuit board and then fixed by a tablet press, which makes high requirements on the operating ability of the operator, and the assembly efficiency and yield rate are not high, which makes the production cost high. Therefore, it is necessary to design a touch switch to solve the above problems. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a touch switch, which solves the problem that the prior touch switches are all installed manually, resulting in low assembly efficiency, low yield rate and high production cost.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a touch switch, comprising a base, on which a wiring pin connected to the inside is arranged, characterized in that an upper switch cover and a lower straight plug plate are respectively arranged at the upper and lower ends of the base, a button passing through the upper switch cover is arranged at the upper end of the base, and inserts are respectively arranged on both sides of the lower straight plug plate, the inserts are arranged perpendicular to the plane of the lower straight plug plate, and positioning pins extending away from the lower straight plug plate are arranged on the inserts, the positioning pins are in the same direction as the wiring pins, and a positioning hole is arranged on the lower straight plug plate.

[0006] The utility model is further configured as follows: the lower straight plug plate is provided with a trapezoidal thin plate protruding outward, and the trapezoidal thin plate is located in the middle of the positioning pins on both sides.

[0007] The utility model is further configured as follows: the upper and lower ends of the base are respectively provided with circular array positioning shafts, the positioning shafts respectively pass through the upper switch cover and the lower straight plug plate, and are fixed by riveting with an assembly machine.

[0008] The utility model is further configured as follows: the upper switch cover and the lower straight plug plate are adapted to the shapes of the upper and lower surfaces of the base.

[0009] In summary, the utility model has the following beneficial effects:

[0010] 1. Compared with the prior art, the upper switch cover plate and the lower straight plug plate provided in the present invention make the overall size of the touch switch smaller than that of the prior art. The prior art touch switches are all installed on the circuit board manually, which cannot ensure the product accuracy and has high operation difficulty. However, the present touch switch can be installed on the circuit board by a mechanical arm and then fixed by a tablet press, which ensures the installation accuracy of the overall product, greatly improves the yield rate, and greatly improves the work efficiency.

[0011] 2. Compared with the prior art, the touch switch of the utility model splits the existing touch switch cover into an upper switch cover and a lower straight plug plate, so that when installing and assembling, the upper and lower ends can be riveted and installed at the same time, and after the split design, manual installation and fixing are not required during assembly, thereby greatly increasing the installation efficiency and yield rate, thereby saving costs.

[0015] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0016] This embodiment discloses a light touch switch, such as Figure 1-2As shown, it includes a base 1, on which a wiring pin 2 connected to the inside is arranged, and is characterized in that: an upper switch cover 3 and a lower straight plug board 4 are respectively arranged at the upper and lower ends of the base 1, a button 5 passing through the upper switch cover 3 is arranged at the upper end of the base 1, and plug pieces 401 are respectively arranged on both sides of the lower straight plug board 4, and the plug pieces 401 are arranged perpendicular to the plane of the lower straight plug board 4, and a positioning pin 402 extending away from the lower straight plug board 4 is arranged on the plug piece 401, and the positioning pin 402 is in the same direction as the wiring pin 2, and a positioning hole 6 is arranged on the lower straight plug board 4. The present touch switch splits the cover plate of the existing touch switch, thereby providing an upper switch cover 3 and a lower straight plug plate 4, and thus no manual assembly is required during the assembly process, and the entire assembly is assembled and installed mechanically, thereby increasing work efficiency, and since the split into the upper switch cover 3 and the lower straight plug plate 4 makes the outer dimensions of the peripheral side of the touch switch smaller, when the present touch switch is installed on the circuit board, it can be installed on the circuit board by a robot, and then fixed by a tablet press, so that the present touch switch does not need to be manually installed on the circuit board by an operator, and since manual installation is replaced by robot installation, the overall installation accuracy is greatly improved, and no human assistance is required for installation, thereby greatly improving the installation efficiency.

[0017] The utility model further provides a trapezoidal thin plate 7 protruding outward on the lower straight plug board 4, and the trapezoidal thin plate 7 is located in the middle of the two side positioning pins 402. The outwardly protruding trapezoidal thin plate 7 increases the contact area between the lower straight plug board 4 and the circuit board, making the overall installation connection more stable.

[0018] The utility model further provides a circumferential array of positioning shafts 8 at the upper and lower ends of the base 1, respectively. The positioning shafts 8 pass through the upper switch cover 3 and the lower straight plug plate 4 respectively, and are fixed by riveting through an assembly machine. The provided positioning bosses are used to install and position the upper switch cover 3 and the lower straight plug plate 4, and then the positioning bosses are riveted and fixed by a machine, so that the upper switch cover 3 and the lower straight plug plate 4 are fixed on the base 1.

[0019] The utility model further arranges the upper switch cover 3 and the lower straight plug plate 4 to match the upper and lower surfaces of the base 1, so that the overall size of the touch switch is smaller and the installation and clamping of the manipulator is more convenient.

[0020] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the design concept of the present invention should be included in the protection scope of the present invention.
